commit fa0dc04d upstream. Dmitry reported a struct pid leak detected by a syzkaller program. Bug happens in unix_stream_recvmsg() when we break the loop when a signal is pending, without properly releasing scm. Fixes: b3ca9b02 ("net: fix multithreaded signal handling in unix recv routines") Reported-by:
